基于多源数据的线路保护通道异常关联分析方法
Anomaly Correlation Analysis Method for Line Protection Channel Based on Multi-Source Data
摘要
Abstract
In order to ensure the reliable operation of the main protection of the high-voltage power grid, the protection channel, router configuration and channel alarm data source distribution of high-voltage power grid are analyzed, and a corelation analysis method based on multi-source data for protection channel anomaly positioning is proposed, which comprehensively utilizes relay protection fault information system and communication network management system. Dynamic information such as communication resource management and control system, maintenance system and EMS system are deeply explored. The time synchronization technology among multiple systems based on information fuzzy matching and the dynamic information association technology based on multi-source information fusion are studied, and the automatic alarm and fault location of the protection channel abnormal fault are realized. The ground fault disconnection assistance decision based on the channel anomaly is also provided. The analysis results of the example demonstrate the effectiveness and accuracy of the method.关键词
